  • Publication number: 20210303173
    Abstract: Embodiments of the present disclosure provide a data processing method, a controller, a storage device, and a storage system. The controller adds an execution time of an IO request to the IO request, and the execution time is used to instruct the storage device to complete the IO request before the execution time expires. The controller sends, to the storage device, the IO request to which the execution time is added. When receiving the IO request, the storage device can execute the IO request based on the execution time of the IO request.

  • Patent number: 10261906
    Abstract: A data accessing method includes: determining whether a preset cache area has cached data that a read target address points to when receiving a read instruction that includes the read target address; and finding a cache address corresponding to the read target address according to a first mapping relationship if the preset cache area has cached the data that the read target address points to, and reading data that the cache address points to from the preset cache area, where the first mapping relationship is used to record a correspondence between the target address and the cache address; orreading, from non-volatile storage space, the data that the read target address points to if the preset cache area has not cached the data that the read target address points to. By means of the method, data read errors caused by write interference can be reduced.
